[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] like Figures 1 to 8 As shown, a dust cleaning mechanism for the inside of a diesel generator set includes a generator set housing 1, a cleaning mechanism and a vacuum cleaner 2. A double door 14 is provided on the side wall of the generator set housing 1. The double door 14 is opened, the cleaning mechanism is placed into the generator set housing 1, and then the double door 14 is closed.

[0032] A heat dissipation port 11 is disposed on the top of the generator housing 1 , the cleaning mechanism is disposed inside the generator housing 1 , and the vacuum cleaner 2 is disposed above the heat dissipation port 11 to perform vacuuming.

[0033] The cleaning mechanism includes a mounting seat 3, an adjustment seat 4, a first cleaning brush 5 and a second cleaning brush 6. A dual-axis motor 31 is arranged inside the mounting seat 3. Both ends of the dual-axis motor 31 are connected to a first screw rod 32. The first screw rod 32 is rotatably connected to the inner side wall of the mounting seat 3 respectively. The adjustment seat 4 is arranged at both ends of the dual-axis motor 31. A mounting block 33 is arranged at the bottom of the adjustment seat 4. The mounting block 33 is arranged on the first screw rod 32.

[0034] A stepper motor 41 is arranged on the top of the adjustment seat 4, and the output end of the stepper motor 41 passes through the top of the adjustment seat 4 and is connected to a second screw rod 42, an adjustment block 43 is arranged on the second screw rod 42, and the adjustment block 43 is connected to the first cleaning brush 5, a guide block 51 is arranged on the side wall of the first cleaning brush 5, a guide groove 61 is opened on the side wall of the second cleaning brush 6, a guide rod 62 is arranged in the guide groove 61, and the guide block 51 is slidably matched with the guide groove 61.

[0035] When cleaning is required, the dual-axis motor 31 is started, driving the first screw rod 32 to rotate, thereby driving the adjustment seat 4 and the first cleaning brush 5 to move along the inner wall of the generator housing 1. When the first cleaning brush 5 is connected to the inside of the generator housing 1, the second screw rod 42 is driven to rotate by the stepper motor 41, driving the first cleaning brush 5 to move up and down along the inner wall of the generator housing 1 to clean the dust; when the first cleaning brush 5 moves horizontally, it moves along the guide groove 61 of the second cleaning brush 6 through the cooperation of the guide block 51 and the guide rod 62, keeping the relative position of the second cleaning brush 6 and the first cleaning brush 5 stable, and the first cleaning brush 5 can drive the second cleaning brush 6 to move and clean synchronously when moving vertically. During the cleaning process, the vacuum cleaner 2 continues to work, sucking and discharging the stirred dust outside the generator housing 1 through the heat dissipation port 11, thereby improving the efficiency of dust cleaning.

[0036] A dustproof mechanism is provided at the heat dissipation port 11, and the dustproof mechanism includes a mounting plate 7 and a filter screen 77. The mounting plate 7 is provided on the heat dissipation port 11, and a plurality of openings 71 are provided on the outer wall of the mounting plate 7, and a slide groove 72 is provided on the inner wall of the mounting plate 7. The side walls on both sides of the filter screen 7 are slidably matched with the slide groove 72.

[0037] By providing the mounting plate 7 and the filter 77, while dissipating heat, dust and impurities can be effectively blocked from entering the generator housing 1, protecting the internal components from erosion and wear, thereby extending the service life of the generator set. At the same time, by providing the slide groove 72, the stability of the installation of the filter 77 is improved, and the removal and cleaning of the filter 77 are facilitated, thereby improving the cleaning efficiency.

[0038] A slot 12 is provided on one side of the heat dissipation port 11, and a card slot 13 is provided on the other side. An insert block 73 is provided on one side of the mounting plate 7, and a positioning block 74 is provided on the other side. The insert block 73 is adapted to the slot 12. A spring 75 is provided in the positioning block 74, and one end of the spring 75 is connected to a card block 76, and the card block 76 is adapted to the card slot 13. A limiting slot 741 is provided on the positioning block 74, and a pull plate 762 is provided on the top of the card block 76. The pull plate 762 passes through the limiting slot 741 to the top of the positioning block 74, and the pull plate 762 is slidably matched with the limiting slot 741.

[0039] During installation, first align the insert block 73 on one side of the mounting plate 7 with the slot 12 on the heat dissipation port 11 and gently push it in to achieve preliminary fixation. While the insert block 73 is inserted into the slot 12, the clamping block 76 in the positioning block 74 automatically pops out under the action of the spring 75 and matches with the clamping slot 13 on the heat dissipation port 11 to achieve secondary locking. At this point, the mounting plate 7 is firmly fixed on the heat dissipation port 11.

[0040] When the installation plate 7 needs to be removed, the user only needs to gently pull the pull plate 762 above the positioning block 74. The movement of the pull plate 762 will drive the clamping block 76 to slide in the limiting groove 741 and compress the spring 75, so that the clamping block 76 is disengaged from the clamping groove 13. Then, the installation plate 7 can be removed from the heat dissipation port 11.

[0041] Through the cooperation of the slot 12, the card slot 13, the insert block 73 and the card block 76, the mounting plate 7 is double locked, ensuring its stability on the heat dissipation port 11. At the same time, the design of the pull plate 762 allows the user to easily control the ejection and retraction of the card block 76, so as to facilitate the removal and replacement of the mounting plate 7, and then regularly clean and replace the filter 77 to maintain its good filtering performance.

[0042] A rounded corner 761 is provided on one side of the clamping block 76 facing the clamping slot 13 .

[0043] By providing a rounded corner 761 on the side of the block 76 facing the slot 13, the direct contact area between the block 76 and the edge of the slot 13 can be reduced when the block 76 is inserted into and removed from the slot 13, thereby reducing friction and wear, helping to protect the integrity of the block 76 and the slot 13 and extending their service life.

[0044] The first cleaning brush 5 and the second cleaning brush 6 are perpendicular to each other in projection on a horizontal plane, and the first cleaning brush 5 and the second cleaning brush 6 clean the inner side wall of the generator set housing 1 at the same time.

[0045] During the cleaning process, the dual-axis motor 31 drives the first screw 32 to rotate, driving the first cleaning brush 5 to move horizontally along the inner wall of the generator housing 1. At the same time, the stepper motor 41 drives the second screw 42 to rotate, driving the first cleaning brush 5 and the second cleaning brush 6 to adjust in the vertical direction. Since the projections of the two on the horizontal plane are perpendicular to each other, they can clean the inner wall of the housing at the same time. In addition, the cooperation of the guide block 51 and the guide groove 61 ensures that the second cleaning brush 6 can move synchronously with the movement of the first cleaning brush 5, thereby achieving all-round cleaning.

[0046] Ear plates 34 are provided on both sides of the mounting seat 3 , and vertical rods 35 are provided on the ear plates 34 . A limiting block 63 is provided on the side wall of the second cleaning brush 6 . The vertical rod 35 passes through the limiting block 63 and slidably cooperates with the limiting block 63 .

[0047] Through the cooperation of the ear plate 34, the vertical rod 35 and the stopper 63, the second cleaning brush 6 is better supported and positioned during the movement, thereby enhancing its stability. Through the sliding cooperation with the vertical rod 35, the second cleaning brush 6 can be flexibly moved and adjusted in the vertical direction to adapt to different cleaning positions and angles.

[0048] Working principle of the present invention: When cleaning, open the double door 14 on the side wall of the generator housing 1, put the cleaning mechanism in, and then close the double door 14. Pull the pull plate 762 above the positioning block 74. The movement of the pull plate 762 will drive the block 76 to slide in the limit groove 741 and compress the spring 75, so that the block 76 is disengaged from the groove 13. Then, the mounting plate 7 can be removed from the heat dissipation port 11. Align the output end of the vacuum cleaner 2 to the heat dissipation port 11.

[0049] The dual-axis motor 31 is started to drive the first screw rod 32 to rotate, thereby driving the adjustment seat 4 and the first cleaning brush 5 to move along the inner wall of the generator housing 1. When the first cleaning brush 5 is connected to the inside of the generator housing 1, the second screw rod 42 is driven to rotate by the stepper motor 41, driving the first cleaning brush 5 to move up and down along the inner wall of the generator housing 1 to clean the dust; when the first cleaning brush 5 moves horizontally, it moves along the guide groove 61 of the second cleaning brush 6 through the cooperation of the guide block 51 and the guide rod 62, keeping the relative position of the second cleaning brush 6 and the first cleaning brush 5 stable, and the first cleaning brush 5 can drive the second cleaning brush 6 to move synchronously and clean when moving vertically. During the cleaning process, the vacuum cleaner 2 continues to work, sucking and discharging the stirred dust outside the generator housing 1 through the heat dissipation port 11, thereby improving the efficiency of dust cleaning.
